Description

Promac Rubber Duck Seal Flex is a superior acrylic matt finish high build flexible fibre-reinforced waterproofing and all-weather resistant coating. Promac Rubber Duck Seal Flex is applied as a thick liquid paste forming a seamless, decorative and flexible membrane. It prevents water penetration and extends the life of the roof or structure. Promac Rubber Duck Seal Flex serves ideally as an anti-drum coating on air conditioning ducts.

• SURFACE PREPARATION: NEW SURFACES: Ensure surfaces are in sound condition, dry (15 % moisture maximum), clean and free from any contaminants such as dust, dirt, rust, salt, algae and grease. Remove all loose materials mechanically, with a wire brush, or by water or sand blasting, then thoroughly clean surfaces with a suitable Multi-Prep Surface Cleaner. Metal surfaces must be free of rust. Metal or galvanized surfaces must be primed with quality anti-corrosive metal primer or metal etch primer. (Prime metal fasteners (screw/nail heads) with a suitable metal primer). Raw brick walls apply one coat of a suitable Promac Bonding Liquid followed by one coat of a suitable Promac Plaster Primer. Cement, masonry, plastered walls, concrete, fibre cement, cementitious tiles, timber and building boards apply one coat of a suitable Promac Plaster Primer. ?

• PREVIOUSLY PAINTED SURFACES: Ensure surfaces are dry (15 % moisture maximum), in sound condition and clean. Restore to a sound strong surface before repainting. Remove all loose materials mechanically, with a wire brush, or by water or sand blasting, then thoroughly clean surfaces with a suitable multi-prep surface cleaner. Bare metal or galvanized surfaces must be primed with a suitable Promac anti-corrosive metal primer or metal etch primer. (Prime metal fasteners (screw/nail heads) with a suitable Promac metal primer). Friable previously painted acrylic surfaces, after cleaning, apply one coat of a suitable Promac plaster primer. Friable previously painted enamel surfaces, after cleaning, apply one coat of a suitable Promac bonding liquid. 

• FIRST COAT: Apply undiluted Promac Rubber Duck Seal Flex at a uniform wet film thickness of 1400 μm or 0.6 – 0.7 m²/litre. Allow to dry for at least 12 hours before continuing.

• SECOND COAT: Apply a second coat undiluted of Promac Rubber Duck Seal Flex at right angles to the first coat, at a uniform wet film thickness of 1400 μm or 0.6 – 0.7 m²/litre. 

• JOINTS: While still wet with a fresh coating, embed non-woven polyester fabric membrane into the first coat of Promac Rubber Duck Seal Flex and saturate. This increases the film strength over joints.   

• PRECAUTIONS – Roof Slopes: Make sure that the slopes are such that they prevent water from ponding (Minimum slope of 2 – 4°). Make sure that the slopes are even along the roof.
